Once a thread is resolved, it stays that way. Replying to a resolved thread no longer reopens it automatically, so a quick follow-up doesn’t bring a settled decision back up for debate.
Follow up freely. Add a note, a link, or a screenshot to a resolved thread, like “this shipped today,” and it stays resolved.
Reopen only on purpose. Tick Reopen thread as you reply, so everyone sees why it’s back.
Agents follow the same rules. Coding agents and other connected agents can reply to a resolved thread without reopening it.
